There's no `z--` in the code you posted, but I think I still get what
you mean (Temp--).

These initialisations are superflous and hence confusing, as you
immediatelly re-initialise these variables with different values.

This actually does not get used at all (apart from decrementing it).

Don't use `//` for comments, at least in newsgroups, as it may foul the
quoting.

I guess `Temp` is a leftover from a different way of implementing this.
E.g. `Temp` could be used instead of `Row` in a `while` loop.
int Temp = PatternSize;
while (Temp)
{
/* do stuff with Col; use Temp instead of Row (not a straight
replacement!) */;
--Temp;
}
OTH, you could also use PatternSize. C passes arguments by value, so
you wouldn't mess whatever is passed in the function call.
